Power supply apparatus with vibration absorbing member for sliding structure

Abstract

A power supply apparatus for a sliding structure includes a wire harness 10 which is extended from a body 5 to a sliding structure, an elastic member 40 for urging the wire harness 10 in a warp absorbing direction, a harness supporting member 50 1 mounted on the elastic member, on which the wire harness 10 is placed, a curved portion protection member 70 which accommodates a curved portion 12 of the wire harness 10 at an intermediate position in a longitudinal direction thereof, and an unusual sound suppressing portion 511, 512 for preventing unusual sound from being generated when the harness supporting member 501 hits against the curved portion protecting member 70. As the unusual sound suppressing portion, projections 511 and 512 to be in contact with the curved portion protecting member 70 are attached to the harness supporting member 50 1 . Because of the above configuration, even when vibration is applied to an engine or car body, unusual sound will not be generated.

1. A power supply apparatus for a sliding structure comprising:
 a wire harness extended from a main body to a sliding structure;  
 an elastic member for urging said wire harness in a warp absorbing direction;  
 a harness supporting member mounted on the elastic member, on which the wire harness is placed;  
 a curved portion protecting member which movably accommodates a curved portion of the wire harness at an intermediate position in a longitudinal direction thereof; and  
 an unusual sound suppressing portion for preventing unusual sound from being generated when the harness supporting member hits against the curved portion protecting member.  
 
   
   
     2. A power supply apparatus for a sliding structure according to  claim 1 , wherein said harness supporting member is provided with a projecting portion to be in contact with said curved portion protecting member, said projection serving as said unusual sound suppressing portion. 
   
   
     3. A power supply apparatus for a sliding structure according to  claim 2 , wherein said projecting portion is composed of flexible blades which are projected from both ends of said harness supporting member. 
   
   
     4. A power supply apparatus for a sliding structure according to  claim 2 , wherein said projecting portion is composed of ribs projected from both sides of said harness supporting member. 
   
   
     5. A power supply apparatus for a sliding structure according to  claim 2 , wherein said elastic member is provided with a projecting portion to be in contact with said curved portion protecting member, said projection serving as said unusual sound suppressing portion. 
   
   
     6. A power supply apparatus for a sliding structure according to  claim 4 , wherein said ribs are not in contact with said curved portion protecting member in a state where no vibration is applied to the power supply apparatus. 
   
   
     7. A power supply apparatus for a sliding structure according to  claim 1 , wherein said unusual sound suppressing portion is composed of a ball portion which is to be brought in contact with said curved portion protecting member and an urging member for urging the said ball portion toward said curved portion protecting member. 
   
   
     8. A power supply apparatus for a sliding structure according to  claim 1 , wherein said unusual sound suppressing portion is covered with an applied material with adhesiveness. 
   
   
     9. A power supply apparatus for a sliding structure according to  claim 1 , wherein a soft member to hit against said curved portion protecting member is attached to said elastic member, said soft member serving as said unusual sound generating portion. 
   
   
     10. A power supply apparatus for a sliding structure according to  claim 1 , wherein a soft material to hit against said curved portion protecting member is attached to said wire harness, said soft member serving as said unusual sound generating portion. 
   
   
     11. A power supply apparatus for a sliding structure according to  claim 1 , wherein an unusual sound absorbing member to hit against said curved portion protecting member is attached to said harness supporting member, said unusual sound absorbing member serving as the said unusual sound generating portion. 
   
   
     12. A power supply apparatus for a sliding structure according to  claim 1 , wherein said harness supporting member has an attaching hole to which said unusual sound absorbing member is inserted. 
   
   
     13. A power supply apparatus for a sliding structure according to  claim 12 , wherein each of the inlets of the attaching hole substantially corresponds to the external shape of the unusual sound absorbing member, and the central portion of said attaching hole has a smaller size than that of the outer size of the unusual sound absorbing member. 
   
   
     14. A power supply apparatus for a sliding structure according to  claim 11 , wherein said unusual sound absorbing member is one of a plurality of unusual sound absorbing members attached to said harness supporting member. 
   
   
     15. A power supply apparatus for a sliding structure according to  claim 1 , wherein the width of a body of said harness supporting member is shorter than the longer diameter of said wire harness which is elliptical in section so that the one end of said wire harness in the longitudinal direction and the other end thereof serve as unusual sound suppressing portions; and in a state where said sliding structure is closed for a said main body, the wire harness is twisted so that the wire harness placed on said body of the harness supporting member is tilted and then the one and other ends of said wire harness are brought into contact with substrates of said curved portion protecting member. 
   
   
     16. A power supply apparatus for a sliding structure according to  claim 1 , wherein said unusual sound suppressing portion which corresponds to said harness supporting member is formed on a substrate of said curved portion protecting member so as to serve as a relief portion which avoids contact with said harness supporting member. 
   
   
     17. A power supply apparatus for a sliding structure according to  claim 16 , wherein said relief portion is a through-hole formed in each substrate. 
   
   
     18. A power supply apparatus for a sliding structure according to  claim 16 , wherein said relief portion is a concave portion or relief groove formed on each substrate. 
   
   
     19. A power supply apparatus for a sliding structure according to  claim 16 , wherein in place of said relief portion, a projection to be in contact with said harness supporting member is attached to each substrate of said curved portion protecting portion.
